"AUTOMATIC CRANK-PIN OILER.

SPECIFICATION forming part of Letters Patent No. 532,208, dated January 8, 1895. Application filed January 18, 1894. Serial No. 497,274- (No model.)

To all whom it may concern:

Be it known that I, JOSEPH MILLER, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Automatic Crank-Pin Oiler, of which the following is a specification.

This invention relates to automatic oilers for moving parts of machinery; and it has for its object to efiect certain improvements in that class of oilers employing self-wipers which are adapted to be used in connection with the lubrication of crank-pins, crossheads, or other moving parts of a machine where continuous movement is necessary.

To this end the main and primary object of the present invention is to construct an automatic oiler of this type, which shall have a positive action without any attendant waste of oil, while at the same time providing eflicient means for a constant feed of oil to the part or parts to be lubricated without spraying or scattering the oil, which is common in other oilers of the same type.

With these and other objects in view, which will readily appear as the nature of the invention is better understood, the same conpin strap E,

sists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the drawings:Figure 1 is a perspective view showing myimproved oiler arranged in position for oiling the crank pin of an engine. Fig. 2 is an enlarged vertical sectional view of the entire device showing the wiper blade about to wipe or scrape the oil pad and thereby feed the crank-pin. Fig. 3 is a detail in perspective of the looped pad spring. Fig. 4 is a similar View of 'the wiper cup showing the wiper blade detached.

Referring to the accompanying drawings, A represents an ordinary engine standard carrying a bearing in which is journaled the drive shaft B, at one end of which is arranged the ordinary crank G which carries at its free end the crank pin D, embraced by the crank at one end of the pitman F. Conveniently arranged to the revolving crank C, is the bracket standard G, having a lower flanged end g, which is usually secured on top of the standard A, of the engine, and said bracket standard G, accommodates thereon a verticallyadjustable clamp H, having right angularly disposed openings h, one of which fits over the standard G, and the other of 55 which adj ustably receives one end of the bracket arm I. The adjustable clamp H, is held in any adjusted position on the standardG, by means of a set screw J, and a similar set screw J, holds the bracket arm in any 6o adjusted position.

The bracket arm I, is adapted to be properly adjusted at one end in the clamp on the standard G, so as to bring its outer end in a .line directly above the circle of movement of the crank pin D, and said outer end of the bracket arm is provided with a threaded opening K, to removably receive the lower thread-V ed end or neck L, of an "ordinary oil cup N, which is adapted to hold the supply of lubricating oil which isto be fed to the crank pin of theengine. The lower threaded end L, of the oil cup M, or at least theoil discharge neck thereof is adapted to removably clamp in position on the outerfiattened end of the arm I, the top or upper side elongated looped pad spring N.

The looped pad spring N, is formed of a continuous strip of spring metal and is adapted to yield sufficiently to the contact of the wiper, to be referred to, as to insure a positive operation of the oiler, and prevent spraying of the oil. The said looped spring is provided with aligned top and bottom openings 0, the-upper one of which accommodates the lower threaded neck L, of the oil cup M, which is disposed in a direct line with the lower one of said openings 0, and is adapted to allow the oil flowing from the cup M to drop directly into said lower one of the spring openings, at which point the oil is absorbed by anabsorbent oil pad P, suitably fastened to the lower outwardly bowed side of said looped spring.

The absorbent oil pad P, may be of any suitable material such as sheep wool, or the like, and is adapted to be kept saturated with a supply of oil, which is to be wiped or scraped therefrom during the movement of the crank pin or other piece of machinery, in connection with which the oiler is employed.

The strap E, embracing the crank pin A, is provided with the usual threaded oil hole Q, in the top, leading to the crank pin, and adapted to-removably receive the lower threaded end of the oiling tube R, towhich is secured a wiper cup S, and said wiper cup S, is adapted to collect all drippings of oil which are directed into the oil pocket s, in the bottom of said cup, from which pocket the oil drains through the oil drain opening T, in the upper .threaded end V, of the tube B, into said latter tube, so as to feed onto the crank pin.

The upper threaded end U, of the oiling tube R, is adapted to detachably receive the lower threaded end of the wiper tube V, which is provided in such lower end with an oil opening 1/, adapted to register with the opening T, and fitted onto the upper end of the tube V, and projecting there-above is the curved wiper blade W. The wiper blade W, is struck on a curve so as to direct the oil caught thereby into the tube V, and the opposite lower edges of the curved wiper blade are curved in as at X, to partly inclose the upper end of the tube V, and thereby insure a more positive feed of the oil from the wiper blade into the oiling tube of the attachment.

The operation of the oiler will be easily understood by those skilled in the art, it being clearly seen that, at each revolution of the crank shaft, the wiper blade is carried against the oil pad P, from which is scraped or wiped a quantity of oil that is directed through the tubes V and R, onto the crank pin, and any drippings of oil which work into the cup S, around the tube V, escape through the drain opening T, into the oiling tube, so that no oil is wasted during the operation of the machinery with which the oiler is connected.

The herein described automatic oiler may be used in connection with the eccentric of an engine, or with any other moving part thereof as well as in connection with the crank 40 pin, and I will therefore have it understood, that changes in the form, proportion and the minor details of construction, may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is- I In an automatic oiler, the combination with a stationary bracket, a looped pad-spring removably secured on said bracket and consist ing of a single continuous strip of spring metal having aligned oil openings and the lower side of which is normally outwardly and 5-5 downwardly bowed and adapted to yield upwardly, and a pad secured to the outer face of the lower side of said spring; of a wiper cup adapted to be attached to the moving part of a machine and provided with a depressed bottom oil pocket, and an exteriorly threaded oiling tube arising from said pocket and having an opening leading therefrom, and a wiper tube detachably fitted onto said oiling tube and provided at its inner end with an oil opening registering with that in said oiling tube and at its outer end with a curved metallic wiper blade having lower inwardly curved edges X to guide the oil into the upper end of the wiper tube, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in. the presence of two witnesses.

JOSEPH MILLER.
